How a studio engagement runs, from the first call to the handover
AppVerz takes on a handful of product engagements a year. This is the shape every one of them takes: a thirty-minute call, a written scope within a week, working software every week after that, and a handover the client's own team can run.

Space Lens and Disk: two ways to look at a full Mac

Finding duplicate files on a Mac: what counts, what does not, and what to keep

The one delete path: how SweepyMac is built so it cannot delete the wrong thing
Every removal in SweepyMac goes through a single function with a single guard. Each module publishes the folders it is allowed to clean, the guard rejects anything outside them, and the four permanent actions are fenced off separately. A look under the hood.
